As long as you can run League of Legends on Windows 7(which you should be able to), you can use the collector's pack, since that is redeemed in the game client store.
Yes League of Legends does work on windows 7, i have windows 7 and it works just fine, you may need to reload it if it doesnt pop up the first time because that has happened to me, but otherwise you should be fine
Currently League of Legends does NOT work on iPod. This could change in the future, but is probably not going to happen.
Yes, they work on every other windows version.

Videos made in Windows Vista will not work in Windows XP because the formats used to create the newer version of a WMM project are not available on the older version of XP.
No, sure won't. You need a Mac key for a Mac version and a Windows key for a Windows version. Programming between Mac and Windows is different.

It is not possible to install Windows Media Player 10 on Windows 98. The last version that will work is version 9.
If I'm not mistaken the pvpnet patcher kernal is part of the client. Looking at the name I guess that it needs to connect to the league of legends servers to work properly. If it has problems it may crash. The best place to ask these sorts of questions would be on the league of legends forums.
